You don't need a driver for SP-300 in Windows 8. Even if it does not recognize the device and an unspecified device sits in the Devices folder, you can use VersaWorks to drive it as it sees the printer without it being correctly registered as a printer in Windows 8.

Sorry , your right , I was reading the panel at side but the display does say a 300V , so should this definitely work with windows 8 ?
As I am still getting that 1311: source file file not found message ?? even after downloading the fix you suggested .

Error 1311 normally means you are tryign to install the software directly from the zip archive.

Did you download the VersaWorks in a zip file? If so then you need to Right click the zip archive and extract it to a new folder ("Extract All.."), then open the new folder and run the Setup.exe from there.

Cheers Tom . I did extract it , But now have Re installed windows as well , updated everything. Versaworks seems to load but right at the last few seconds gives an error message -
